What should I do if I have a little cold before going abroad for medical examination? (wait online! ! ! Plus points! ! ! )

It is not too late. Wash your nose and drink plenty of water. Wash your nose thoroughly, preferably the nasopharynx. Drink water and boiled water, but don't drink tea.

A large number of bacteria, viruses, fungi and other pathogenic bacteria float in the air we breathe every day, and these pathogenic bacteria continue to enter our nasal cavity through our breath. But generally speaking, the detoxification system of the nasal cavity itself can transport pathogenic bacteria to the nasopharynx within 15 to 30 minutes, and finally enter the stomach for digestion. At this time, the number of viruses is always within the range that the nasal immune system can bear, so we will not get sick.

However, when cold, rain and other inducing factors, menstruation, pregnancy and other physiological factors can reduce the detoxification function of the nasal cavity, the virus can stay in the nasal cavity for a long time. At this time, the virus can breed more viruses than the nasal immune system can bear, and the virus will invade the human body and we will catch a cold. Patients with rhinitis are more obvious, that is, they are more likely to catch a cold. Later, the virus base in the nasal cavity was larger, and the number of viruses increased faster, so a large number of viruses began to spread to other parts of the body, and the systemic symptoms of colds began to appear.

Therefore, when you catch a cold, your nose acts as a virus base camp. As long as we insist on washing the nasal cavity with warm salt water and cleaning up a large number of viruses in the nose, fewer and fewer viruses will invade the human body. Finally, the number of viruses in the nasal cavity can be reduced to the range that the nasal immune system can cope with. At the same time, the human immune system will soon kill the virus that enters the human body.

Therefore, buying a nasal lavage pot, washing the nasal cavity with warm salt water when catching a cold, and trying to keep no excess nasal mucus in the nasal cavity can fundamentally solve the virus problem. This method can cure a cold in 2 to 4 days without taking any medicine. Washing your nose in the morning and evening can prevent colds to a great extent and greatly reduce the chance of catching a cold.

At the same time, because the flu and cold make people sick in the same process, but the types of viruses are different. Therefore, this method can also relieve flu symptoms, treat flu and prevent flu at the same time, and is suitable for all kinds of flu.

After curing the cold in this way, reduce the frequency of nose washing to morning and evening, so that you can slowly recuperate your nose and treat rhinitis.
